I am updated to the latest version 4.4.2(T217SVPUBOH1) yet I system update won't go away form the notification bar-check mark- or the pull down menu. Is there anyway to get rid of this?
What happens when you tap that notification? Does it send you to the Settings>About Tablet>System Updates screen, which only tells you it's up to date? If so, try wiping the cache partition: https://support.t-mobile.com/docs/DOC-16226
Go to the App Manager. Can you select DM Service there? If so, try Clear Cache. If that doesn't work, Clear Data as well.
No, I can't uncheck this.Are you able to uncheck Show Notifications for com.samsung.syncservice?
That's odd. I'm not sure if this will help, and it's a minor hassle, but you could try Clearing Data from the TouchWiz launcher. This will wipe the homescreens clean, so you'll have to set them back up again. Go to the App Manager, select TouchWiz, and Clear Cache/Clear Data. Now see if the notification persists.
